Patented Sept. 16, 19I3.

Original application filed April 15, 1909, Serial No. 490,079. Divided and this application filed January 11, 1910. Serial No. 537,568.

.71. all whom it may concern Be it known that I, STUART W. GRAMER, a citizen of the United States, residing at Charlotte, in the county of Mecklenburg and State of North Carolina, have invented certain new and useful Improvements in Air- Conditioning Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to apparatus for treating air, whereby the air is cleansed of its impurities, and is conditioned by the addition or subtraction of moisture and heat as may be desired.

The object of this invention is to provide an apparatus whereby air cleansing, moistening, heating and cooling are attained as heretofore in similar types of apparatus, with the further advantage that cooling may also be continued even though moistening be discontinued, and without the aid of refrigeration, the circulation of cold water, or other liquids, or the like.

The invent-ion consists in certain improvements which will be fully disclosed in the following specification and claims.

This application is a division of my application for a patent filed April 15th, 1909, Serial Number 490,079.

In the accompanying jdrawings, which form part of this specification :Figure 1 represents an isometric view of an apparatus using a single cold air tube, bein an adaptation of my invention to the individual head type of air conditioning apparatus. Fig. 2 represents a plan view of the same. Fig. 3 represents a side elevation of the same, and Fig. 4: represents a side elevation of a modification of the same type of apparatus.

Reference being had to the drawin s and the designating characters thereon, t e numeral 1 indicates an inner tube which forms the spray or moistening chamber, 2 an annular air cooling chamber between the tube 1 and the outer tube 3. 4: the spray-heads, 5 and 6 the fans. 7 and 8 the ducts for supplying air from outside the building and 10, 11 the dampers.

The operation of this device is readily discernible Without further elucidation. In the tube 1, one or more spray heads 4. may be used, a fan 5 may be used to move the air in said tube, or it may be moved by the inductive effect of the sprays alone. It will be noticed that in all of the types embodied in this invention, it is possible to control the humidity in a room by opening and closing the damper 12, which either admits the moistened air to the room or directs it put through the root' or side wall of the building as may be desired.

In Fig. 4 air may be supplied from inside the building by a fan 13 to supply the air cooling chamber 2, and air drawn through pipe 14 from outside the building to supply the spray or air moistening chamber. 15 indicates the pipe through which moistened air may be conducted outside the building, under control of damper 12.

Further elucidation is deemed unnecessary, as the foregoing description with the accompanying drawings will suggest to anyone skilledin the art to whic my invention appertains some of the various modifications of which the invention is susceptible.

It is obvious that in lieu of the spray heads shown, other devices may be employed for cooling by the evaporation of the moisture, and that changes in form and arrangement may be made without departing from the spirit of my invention.

Having thus fully described my invention, what I claim is y 1. In an air conditioning apparatus, an air chamber, a fan for producing a current of air through the air chamber, a spray chamber wit in said air chamber, spray heads for moistening, cooling and inducing a secondary current of air through said spray chamber, and means for controlling the supply of air from said fans.

2. In an air conditioning apparatus, a spray chamber, spray heads within said spray chamber, and arranged for inducing a current of air through said spray chamber, an air cooling chamber surrounding said spray chamber, a fan for. producing a current of air through the cooling chamber but closed from the spray chamber, and
